Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482858, here are decompositions:

19 + 31482839 = 31482858
37 + 31482821 = 31482858
59 + 31482799 = 31482858
79 + 31482779 = 31482858
97 + 31482761 = 31482858
149 + 31482709 = 31482858
151 + 31482707 = 31482858
191 + 31482667 = 31482858

Showing the first eight; more decompositions exist.
